Update:

A severe G4 solar storm is expected to hit Earth on June 14, 2025, as reported by NOAA’s Space Weather Prediction Center; solar wind coming from a coronal hole—a region where the Sun’s magnetic field opens into space—is the source. When these charged particles reach Earth, they interact with the magnetosphere, creating an intense geomagnetic storm.

While a Coronal Mass Ejection has not been detected, such a strong storm could trigger a range of effects on Earth. Satellites in low-Earth orbit may experience increased drag, potentially altering their orbits. GPS and aviation systems might suffer from signal disruptions, impacting navigation. High-frequency radio communications, also used by aircraft, may become unstable.

On the positive side, the storm may produce auroras visible in regions much farther south (or north, for our Southern Hemisphere brethren) than usual, including parts of southern Chile, New Zealand, and the northern United States.

Although strong, this storm is not expected to cause a major technological crisis. There have been no signs of coronal mass ejections (CMEs)—large solar plasma bursts—only a continuous high-speed solar wind. The effects may last through the weekend, but agencies do not anticipate severe long-term damage.

This event comes during the peak of Solar Cycle 25, which began in December 2019. Historically, powerful geomagnetic storms have caused significant disruptions, such as the Carrington Event of 1859 and a 1989 storm that took down Quebec’s power grid. More recently, in May 2024, a G5-level storm disrupted satellites and GPS.
